I love to see the creativity that comes out in full force at these things.

I'll go first: My signature has always followed a pattern, of picture, by-line about me, quote. The picture has been the cats of Steely Dan for about 4 or 5 months now. The by-line ("Proud writer, musician, feminist, Mainer, and high school student.") is me in a nutshell, and never changes.
The quote is always one by the pictured. I've been using a different SD song lyric every month or so since I've had Fagen/Becker in my signature. Currently the song lyrics are from "Your Gold Teeth" from the 1973 album
Countdown to Ecstasy: "Even Cathy Berberian knows/There's one roulade she can't sing." Cathy Berberian was a famous, very talented opera singer; a roulade is, according to dictionary.com, "An embellishment consisting of a rapid run of several notes sung to one syllable." So, the pairing here is saying that even the best know there's
something they can't do....Basically, "No one is perfect." Which I think is good advice, though Fagen/Becker intended it as a very sardonic jab at the gambling, crazed, "monkey woman" of the song.

Your turn!
